Algo a destacar es la gran caida de hashrate que hemos visto hace poco que justamente se dio a la misma vez practicamente que el lanzamiento official de BAKKT. De hecho creo que fui el primero en el foro de comentar esta caida. Estoy tratando de averiguar que puede haber hecho que caiga el hashrate. Solo he encontrado una noticia que relaciona un periodo de mantenimiento de una mineria en Kazakhstan en estas fechas. Fuera de esto, las especulaciones al respecto estan a la orden del dia. Desde que hay una manipulacion de mineros para aprovecharse y generar traccion en un trade tipico de "sell the news" y shortear a fondo (con la caida de hashrate justo durante el lanzamiento de BAKKT tendriamos una manipulacion mental del mercado haciendo un efecto bola de nieve). Ya sea o no en colaboracion con el mismo BAKKT que lo veo dificil pero no imposible.

Por si a alguien le interesa, la compañia que emitio el comunicado es "Square Mining Ltd.". A mi me parece muy raro todo esto. Podemos estar ante la tipica caida drastica que se recupera rapido. Si no lo hace, es posible que estemos en bear hasta que el halving surta efecto.

Anyone got a date for the Tyson Fury vs Deontay Wilder rematch? There was a statement by Deontay after Fury won the fight against Wallin. According to him, his next fight is going to be against Luis Ortiz (rematch) by the end of this year and after that he is going to take on Fury (probably around February 2020).

That February 2020 might be move since they need to heal that nasty cut but probably 2020 might be the year for this fight to take place.

After the fight against Fury, Wilder will be up against Andy Ruiz Jr.
This overconfident dude huh, he think that he would win against Fury or he is afraid of Anthony Joshua?

I can see betting games being formed in relation to how long will Tyson Fury take off the game to heal from such massive pierces. Bone was exposed, it was really dangerous to keep that fight going. We saw once again the big machinery of boxing at work, the wouldn't let another flop happening, Tyson was needed to win. Most fighters would have thrown the towel, but Fury's heart is unmatched.

My oiriginal bet still stands: I believe Fury will push Wilder to a decision again, and this time Fury will get an UD. Wilder got pretty much outboxed, but got a single punch, just like Wallins got a lucky punch that cut him, but skills wise, both got exposed.

FUD

let the records state: you fell for FUD



all these websites will soon be reporting "oops, we all accidentally, spookily made the precise same mistake, how could that happen Huh"

make of it what you will

What's important is knowing what caused this. I don't believe in coincidences. Looks like the schelude is right on time for BAKKT launch. Picking up cheap coins to meet contract needs? remember that BAKKT needs to buy Bitcoin as opposed to what was out there thus far on this field. Those people could have contacts with miners. Only a big miner could have done this. I don't believe this is a mistake by a website and the rest are following. Or it just could be good ol "short the news" op.

Maybe it could be related to this:

https://www.globenewswire.com/news-release/2019/09/19/1918342/0/en/Squire-Mining-Operations-Undergo-Temporary-Power-Outage.html

Quote
VANCOUVER, British Columbia, Sept. 19, 2019 (GLOBE NEWSWIRE) -- Squire Mining Ltd. (CSE:SQR | FWB:9SQ | OTCQB:SQRMF) (the “Company”) announced that it has been informed by its hosting provider in Kazakhstan that the facilities housing the Company’s cloud computing fleet will undergo temporary power black-outs.The black-outs are the result of the hosting provider’s power supplier undertaking a necessary upgrade in the substation transformer supplying power to the facility. The upgrades are being carried out to address reliability issues prior to the upcoming winter season.  The Company’s hosting provider has advised that the outage is expected to last between 10 and 14 days.  During this time, some of the Company’s cloud computing fleet located in Kazakhstan will be non-operational and non-profitable for periods but will also accrue proportionally lower electricity costs during such times.

The Company is working with its hosting provider to minimize impact to its operations.

But then again, how big would Kazakhstan be on the mining game to make such a dip?
84  Bitcoin / Bitcoin Discussion / Big drop in hashrate on: September 24, 2019, 04:55:00 PM
I just saw a big drop in hashrate, check this chart:



It's clearly visible from the all time chart, pretty big cut right a couple of hours ago. Upon closer inspection:



From 98EH/s to 63EH/s, we are looking at probably an entire farm being shut down. It's either authorities, an accident, or resetting all systems at once. Hopefully one of our chinese friends can tell us something and report back, because who else is dealing with this hashrate? I know McAffee had something going on but I doubt it's that relevant.

Sigo sin entender por que la gente compraría futuros en vez de comprar los bitcoin directos. Al final ambas son herramientas de inversión. Sin embargo considero que los futuros tienen mas riesgo ya que al ser por un tiempo definido si el día que se cumple la inversión el precio de el bitcoin está bajo entonces perderemos sin tener la opción conocida como 'Holding'.

Ustedes personalmente invertirían en futuros o prefieren comprar la criptomoneda?

Bakkt se supone que a diferencia de la alternativa del NYSE, en este servicio se estarian comprando las cantidades reales de Bitcoin para cerrar los contratos y se enviarian bitcoins directamente a los participantes, en lugar de nunca comprar BTC y hacerlo todo por fiat como se venia haciendo. Si hay grandes posiciones se compraran grandes cantidades y se traducira en el precio aunque es posible que lo compren OTC. No se realmente de donde sacaran las cantidades que se necesiten para cerrar las posiciones y pagar a acreedores.

Hay que tener en cuenta que mucha gente quiere exponerse al mercado de BTC pero no quiere exponerse al riesgo de tener que guardarlos ellos mismos y pone la confianza a un tercero para que los salvaguarde por ellos, como ya pasa con el oro.
86  Local / Español (Spanish) / Re: La Industria Mundial también se ve Beneficiada por Bitcoin y Criptomonedas on: September 24, 2019, 12:47:08 AM
A mi me parece el tipico articulo de "tecnologia blockchain" sin profundizar mucho. Aun no he visto ningun articulo mainstream que deje claro que el termino blockchain, si no esta ligado a un token que sea decentralizado y sea un metodo para incentivar la sostebinilidad de la red, como es el caso de Bitcoin, y este es el unico caso. El resto de aplicaciones de la blockchain, no he visto aun que tenga un objetivo claro o justificacion para venderlo como algo revolucionario. Solo veo articulos vendiendo este tipo de humo.

La realidad es que bitcoin es la unica aplicacion de la blockchain y el resto son cosas negligibles. Puede que haya algun tipo de beneficio en alguna instancia pero estamos hablando de mejorar una gestion de una base de datos vs una red decentralizada de dinero inconfiscable, es ridiculo que esto no se le deje claro a la gente en la prensa mainstream pero es lo que hay.
87  Alternate cryptocurrencies / Altcoin Discussion / Re: Sending multiple queued ETH transactions through an API? on: September 24, 2019, 12:10:52 AM
Hello all,

Is there any Ether wallet management software or some kind of API service other than BitGo that I can use to send queued Ethereum transactions, rebroadcast them automatically if they are out of gas etc. Essentially I need  reliable automatic 24 hour solution for sending ethereum transactions.  For start it is 20-50 transactions a day but it should be able to scale if needed.
Additionally, but not crucial at this moment, i will be needing solution to consolidate multiple ETH inputs to one or more hot or cold eth  wallet / addresses.

All suggestions are welcome, thank you

Theres a dAPP that does exactly this:

You can learn about timenoddes and it's pretty straight forward, it's all on the github documentation.

Also look at this for an alternative: https://mycrypto.com/

Or txpool API:

Txpool

Quote
The txpool API gives you access to several non-standard RPC methods to inspect the contents of the transaction pool containing all the currently pending transactions as well as the ones queued for future processing.

Many ways to do this.

A disappointing ending to the Rodriguez and Stephens fight. An accidental eye poke 15 seconds into the fight ended the match and resulted into a no-contest. Such a shame that after months of preparation, it ended that way. An immediate rematch between the two is a must but it still depends on Stephens condition.

Yeah, it's really disappointing to see the fight ended that way. And it was reported that Stephens has some deep scratch on his eye, hope he can recover soon so that a rematch would happen.

Now that the event is over, looking forward to the main event in the land down under. UFC 243!

I hope the Whittaker vs Adensanya will live up to its hype.

Im way more interested in the BMF belt than whatever UFC 243 has to offer. Adensanya is a pretty good up and coming prospect, but im not confident giving him a win. He hasn't proved to be a draw yet IMO. I don't want my cashflow to get destroyed by doing an unlucky win bet in this one. Sure he's got Anderson and Gastelum on his belt but that isn't enough to start thinking this guy is going to become another cash cow in which you can bet for wins blindfolded Jon Jones style, and that is what some people is trying to sell me, and im still not buying. Let's see how he performs with Whittaker. After 2 Joel wins, if he ends this easily, I may consider him the next safe bet in the game, just like Khabib and Jones.

Yeah, I agree, who would like his bankroll just steam roll with a guy who doesn't proved anything yet except winning against a old Silva and overhype Gastellum? And he is going to face a champion here who is battle tested against one of the feared guy in the division. So let's see how their style make this fight hype or another boring one. I'm not putting any bet on their match though, just wanted to see how either one of them will perform against each other.


They want a new posterboy and looks like Adesananya is going to be one of the future cash cows in the game. Dana White wants to build an undefeated record for him, but now we are going to see his first test. He has started beef with Jon Joes, I think he is delusional. If he doesn't continue picking up his fight in a smart way he is going to end up with a big 1 in his record.

https://www.mmafighting.com/2019/4/12/18308191/jon-jones-responds-israel-adesanya-ufc

He would need to bulk to light heavyweight wereas Jones is a natural light heavyweight fighter. He can never beat him.

89  Bitcoin / Development & Technical Discussion / Re: Self destruct/send coins after X failed pass attempts on: September 23, 2019, 11:49:46 PM
it is both pointless and harmful to the regular users. a lot of them will end up breaking the thing themselves by entering their passwords with typos! besides if someone is trying to brute force your password through the client, there is a much easier way to prevent them from succeeding: 1. use a stronger password than "123", 2. add a simple fail_counter to add a delay like 30 seconds each 3 times they fail!
otherwise those who actually brute force a password, don't use the  client, they open the file itself and you can't do anything about that.

If you were forced at gunpoint to deliver a password, it would be useful to have an alternative that isn't either take a possible beating/end up dead or either hand your hard earned money to said attacker. Right now with wallet.dat we don't have either a way to self destruct or a way to open an alternative empty wallet, or something like that. So I guess people is relying on FDE with hidden volumes? But that has been proven to be demonstrable that the drive contains hidden data. I was wondering if with a contained file like wallet.dat you could hide hidden data. I think Truecrypt volumes are safe when it comes to hidden data but not FDE and you must open the file anyway. I think plausible denniability methods of protection for wallet.dat is worth exploring.

If you have a proper backup setup then entering the password incorrectly by mistake shouldn't be a problem.

The idea is that if someone is constantly failing to enter the correct password to unlock the wallet, the funds would move to an address of choice (which cannot be changed unless you own the password). Another option would be to self destruct the wallet.dat. The point is to avoid people to stop trying to bruteforce the thing. The problem is how to even go about this since someone could just use another client which doesn't have this feature assuming it got added in a Core update. It would at least IMO protect against non sophisticated attackers.
92  Alternate cryptocurrencies / Altcoin Discussion / Re: There has never been a worse time to hold altcoins on: September 22, 2019, 10:43:01 PM


Stop deluding yourselves, the altcoin market is not coming back, and if it does come back, you better dump whatever you have left because there are no chances of it pumping ever again beyond an exit scam. Smart money has learned to stop pumping shitcoins. Altcoin continue to sink against BTC. Dollar valuations don't matter because altcoins have no liquidity outside of BTC, so with BTC pairs going down you are going to lose purchasing power during the process. And still, they eventually keep going down against assorted fiats too.

Bottomline is, you are holding a massive hot potatoes bag by having a diversified "crypto portfolio" in altcoins. Sure there will always be the odd ones that pump, but that's worse than going to the casino. You might as well trade regulated penny stocks if you want to bet on low caps going to the moon, where there are less chances of getting screwed over by massive scammers. At least you surely lower exchange rate risk (and most of those shitcoins are listed in shady exchanges).

It depends.

There are some fundamental issues with BTC that some coins like NANO has resolved.
Some to mention:

* Transaction Fee
* Electricity consumption
* Transaction Time
* Scalability

you have neither of these issues with NANO.



I know something that has low transaction fees, low transaction time, and scales, it's called fiat. You could argue about electricity consumption, however NANO network is tiny. You are also assuming that NANO is truly decentralized. Until NANO or whatever altcoin you want to offer, hasn't had a multi billion $ marketcap with 0 hacks through a decade, and has been attempted to be subverted via forks, then your coin is pretty much worthless and definitely not a BTC replacement.
93  Bitcoin / Bitcoin Technical Support / Re: Wallet passphrase and salt encryption on: September 21, 2019, 06:16:41 PM
My question is as follows: When encrypting BTC Core wallet, is the format as follows: Sha512(passphrase+salt) or Sha512(salt+passphrase) before encrypting with AES256CBC for the wallet? Thanks.

See this:

https://github.com/bitcoin/bitcoin/blob/6b8a5ab622e5c9386c872036646bf94da983b190/doc/README

Quote
Wallet encryption uses AES-256-CBC to encrypt only the private keys
that are held in a wallet.  The keys are encrypted with a master key
which is entirely random.  This master key is then encrypted with
AES-256-CBC with a key derived from the passphrase using SHA512 and
OpenSSL's EVP_BytesToKey and a dynamic number of rounds determined by
the speed of the machine which does the initial encryption (and is
updated based on the speed of a computer which does a subsequent
passphrase change).  Although the underlying code supports multiple
encrypted copies of the same master key (and thus multiple passphrases)
the client does not yet have a method to add additional passphrases.

Summary from PWiulle:

Quote
    The passphrase is converted to a key/iv pair using EVP, with a dynamic number of rounds
    This key/iv pair is used to encrypt a randomly-generated master key, using AES-256-CBC
    The secret part of wallet keys are then encrypted using that master key, again with AES-256-CBC

Just saw this one. Not a bad post per se, but I find it funny due the dodgy grammar:

From my point of view, scam projects have taken away the glory of genuine projects.
Due to too many scams around crypto space, investors are not confident on investing in new projects. It's Becoming very difficult day by day to find out the legitimacy of the projects.
This in turn affecting the projects and result of this is not raising the funds as expected and required for further development of projects. This is daviating projects from their roadmap which is resulting in too much delay or even failure.
Kissing interest in investors is somehow obstacle to growth and further research of dApps projects.
I think, rugulations will solve the topic to great extent, but is there any other way to stop the scamming and not just going away from it?
Please apply your thoughts.

Looks like kissing interests are what is disrupting the altcoin market, of all things. I can't think of a valid context where that word comes from.
97  Alternate cryptocurrencies / Altcoin Discussion / Re: There has never been a worse time to hold altcoins on: September 20, 2019, 04:34:11 PM
The graph looks depressing, but in addition to the picture reinforces your position on altcoins, I have not heard reasoned arguments in favor of the fact that it is necessary to get rid of them right now.

I offered you the only sane argument I can think off: Whales which are still stuck within the 2017 crash holding huge amounts of altcoin bags, planning to do the last exist scam within the next Bitcoin rally. As noobs look at "coinmarketcap" while Bitcoin is on mainstream news when it's about to hit ATH as usual, those whales may attempt to confuse the noob by luring them into buying some of those pumping shitcoins, only to dump on them bigly. This may be the last time for bagholders to leave the crazy train formerly known as "cryptocurrency diversification".

Other than this theoretical exit scam pump, I can't think of fundamentals strong enough for altcoins to maintain any sort of positive traction long end, and this includes Ethereum, Litecoin, Monero and the usual suspects. The ball is on your court to argument why should anyone bother having serious long term hold positions on any of that.

Can you mention how much time did it took to finish the sync?

I can't say for sure as I had some troubles with the last part of the sync and did some experiments etc. But at least, the first half of the blockchain (i.e. +100GB) was downloaded within the first day.
With optimum conditions (fast network and SSD drive) I believe a  clean sync should easily complete within two days on the RPI4B.

I now also got raspiblitz (Bitcoin + LND) up and running :-)
With the small passive heatsink temperature settles at about 68C with some open connections...

I don't think you can extrapolate the remaining half of the blockchain by what amount of time it took to get the first half downloaded. Consider this:

https://jochen-hoenicke.de/queue/#0,all

Unfortunately there isn't older charts that collect this data that I know of, but by looking at that you can see the all time peaks of 2017 during the $20k bubble, that mix of legit traffic + Ver and Bitmain spamming makes that section of the blockchain specially slow to synch in my experience. Maybe it was because it's an HDD and you notice this section less with SSD. When I find some free time I will try for myself and monitor the full sync time and report back.

I almost had a heart attack watching this. Vegas was going crazy the night of the fight when Tyson got that massive cut, TWICE on the same eye. The fight was really near to TKO stoppage which would mean three things:

1) Tyson losses his undefeated record
2) The Wilder rematch gets possibly ruined
3) Massive, epic loses on the gambling scene, and massive wins as well

However there are great news with this bout: This confirms that there isn't room for rigged fights in elite boxing. You couldn't script that mess of a fight. I was expecting a boring one sided match and those cuts made my cortisol rise for the remaining of the fight as we were about to witness the biggest upset ever in possibly any sports.
